导入Tensorflow时如何修复ImportError

Question

我正在尝试在Jupyter笔记本上导入Tensorflow，它给出了如下所述的错误。

这是在错误地运行!pip install -q tf-nightly之后发生的。

我尝试几次重新安装conda和tensorflow，但是每次运行都显示相同的错误：将tensorflow导入为tf

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
ImportError: numpy.core.multiarray failed to import

The above exception was the direct cause of the following exception:

SystemError                               Traceback (most recent call last)
~\Anaconda3\lib\importlib\_bootstrap.py in _find_and_load(name, import_)

SystemError: <class '_frozen_importlib._ModuleLockManager'> returned a result with an error set

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
ImportError: numpy.core._multiarray_umath failed to import

---------------------------------------------------------------------------

Answer 1

请尝试升级numpy。

您可以使用以下对我来说很好的命令。

pip install opencv-python == 3.4.2.17 numpy == 1.14.5
